We experimentally demonstrate a Raman fiber laser based on multiple point-action fiber Bragg grating reflectors and distributed feedback via Rayleigh scattering in an ~22-km-long optical fiber. Twenty-two lasing lines with spacing of ~100 GHz (close to International Telecommunication Union grid) in the C band are generated at the watt level. In contrast to the normal cavity with competition between laser lines, the random distributed feedback cavity exhibits highly stable multiwavelength generation with a power-equalized uniform distribution, which is almost independent on power.
我们通过实验演示了一种基于多点光纤布拉格光栅反射器和瑞利散射分布式反馈的拉曼光纤激光器，该激光器使用了约 22km 的光纤。在 C 波段，我们在瓦级水平上产生了 22 个间隔约为 100GHz 的激光线（接近国际电信联盟的栅格）。与具有激光线竞争的常规腔相比，随机分布式反馈腔表现出高度稳定的多波长产生，其功率均衡的均匀分布几乎与功率无关。
